2. Q.Volusius, a pupil of Cicero in oratory, accompanied Cicero to Cilicia, where he held some office under him. (Cic. Fam. 5.10, 20, ad Att. 5.21.) In one passage (ad Att. 5.11) he is called Cn. Volusius, for there call be little doubt that this Cneius is the same person who is elsewhere called Marcus.
